Provaris Energy advanced DNV approval work for its 25,000 cubic metre LCO₂ tank and completed further stages of its hydrogen prototype during the September quarter. The technical progress came alongside a funding push, with $777,000 in cash at quarter-end and an oversubscribed $914,500 share purchase plan completed after the period.
- DNV review of LCO₂ tank engineering package nearing completion
- GASA planning begins for final ship-application approval pathway
- Hydrogen prototype cylinder and first end-cap completed
- Himile collaboration expands into commercial-scale H₂ tank manufacturing
- $914,500 post-quarter SPP lifts funding, after $777,000 quarter-end cash
DNV approval moves towards a decision
Provaris Energy Ltd (ASX:PV1) has supplied DNV with the additional engineering documentation requested during its review of the company’s 25,000 cubic metre low-pressure LCO₂ tank, leaving the Approval in Principle process pending DNV’s final comments and internal decision. The tank is being developed with Yinson Production for a floating storage and injection unit linked to the Havstjerne carbon capture and storage project off Norway.
The milestone follows the June engineering submission, which covered the structural package for the tank’s FEED phase. Provaris said DNV has treated completion of the review as a high priority, but the AiP award remains pending rather than secured.
GASA work adds another technical gate
While the AiP review continues, DNV, Yinson and Provaris have started planning the next General Approval for Ship Application stage. That work is expected to include further engineering, safety and procedure documentation, non-destructive testing and inspection requirements, plus material, weld-procedure and scaled mock-up testing.
The sequence matters because AiP is not the final class approval for ship application. Provaris and Yinson are also progressing draft agreements for a jointly owned company that would hold equal commercialisation rights to the LCO₂ tank technology and license the design and related services to shipyards and owners of CO₂ maritime infrastructure. Those arrangements have not yet been finalised.
Himile weighs full-scale tank production
Fabrication planning has moved from concept towards industrial practicality. Himile executives visited Oslo for workshops on preliminary production costs, schedules and fabrication design, then inspected Provaris’ robotic welding facility in Fiskå, Norway. Himile is assessing yard upgrades, production hall layouts and fabrication procedures for the first full-scale LCO₂ tanks.
The same relationship is being extended to hydrogen. Following the Himile hydrogen collaboration, the companies are assessing commercial-scale manufacture of tanks for Provaris’ H2Neo carrier and H2Leo storage barge, including automated laser-welding processes and cost estimates to support discussions with K LINE and shipyards.
Hydrogen prototype reaches assembly stage
At Fiskå, Provaris completed the hydrogen prototype’s cylinder and first of two end-caps. The final end-cap is under construction, with assembly and testing plans being developed in parallel. A maintenance issue affecting the welding robot and tracking equipment caused periods of downtime during the quarter, but the company said the equipment has returned to operating capacity and required welding tolerances.
The prototype remains part of Provaris’ pathway towards final marine classification approvals for the H2Neo carrier. The company expects to provide further fabrication and assembly updates in the December quarter, subject to resource availability and a review of the testing and approvals program with DNV.
Funding improves, but the runway remains short
Provaris ended September with $777,000 in cash and reported net operating cash use of $777,000 for the quarter. Including $600,000 of undrawn capacity under its convertible note facility, the Appendix 4C calculated 1.8 quarters of funding at the reported cash burn rate.
That calculation predates the post-quarter share purchase plan. The SPP raised $914,500 before costs after attracting more applications than its $600,000 target, taking the company’s disclosed recent funding to about $1.5 million when combined with the $600,000 convertible note tranche drawn in September. The stronger funding position gives Provaris more room to pursue its technical program, but the company remains dependent on further commercial progress and disciplined capital use while its projects are still moving through approvals, testing and customer discussions.
Bottom Line?
The next valuation-sensitive milestones are tangible: DNV’s AiP decision, GASA testing, prototype completion and a clearer timetable for Himile fabrication. The funding has bought time, not yet commercial certainty.
Questions in the middle?
- When will DNV complete its AiP review, and what technical conditions could remain before GASA testing begins?
- Can Provaris and Himile convert fabrication studies into a priced, scheduled first tank order?
- Will the H2Neo and Nordic supply-chain discussions produce binding shipping or offtake agreements before the enlarged funding buffer is consumed?
